WEATHER STRIP.

Application filed February 4, 1926. Serial No. 85,959.

This invention relates to improvements in metal weather strips and its object is to provide a strip over which the window sash will slide readily without sticking and which at the same time will render the window and window frame sufiiciently tight to prevent the admission of strong drafts of cold air in severe weather.

Simplicity in construction, efiiciency in use and cheapness of manufacture are objectsattained by the present invention. With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claim and illustrated in the accompanying drawing which forms a part of this application and in which- Fig. l is a fragmentary view of a window illustrating the a plication of the strip.

Fig. 2 is an en arged sectional view taken on line 22 of Fig. 1.

Fig. 3 is a fragmentary perspective view of the strip.

Like reference characters denote corresponding parts throughout the several views.

The reference numeral 1 denotes the window frame, 2 the sash and 3, 4 the beads in the frame. To afford a close fit to the sash the latter member is formed with two longitudinal spaced recesses 5,6, one wall of each recess being bevelled and the remaining wall being straight from the lateral edge of the sash to the deepest part of the bevel.

The strip comprises a piece of material having one flat lateral edge 7 that merges into a rib 8 shaped to fit snugly into the recess 5, said rib then merging into the straight base portion 9, which receives that portion of the sash between the grooves 5, 6, which merges into the second rib 10 that fits snugly into the sash recess 6 and then vmerges into the straight base portion 11 that receives a portion of the sash adjacent the recess 6, said base 11 then merging into the rounded resilient edge 12 disposed contiguous to the bead 4. The bead 3 rests upon the strip edge 7. Nails 13 driven through the base port-ions 9, 11 of the stri into the window frame serve to retain sai strip securely in position. The strip is so fitted to the sash as to keep out drafts, the resilient edge 12 serving automatically to cause the strip to conform closely to the sash regardless of expansion or. contraction thereof due to weather conditions, or to wear from use.

lVhat is claimed is The combination with a window comprising a sash having longitudinally extending spaced recesses, one wall of each recess being bevelled, of a weather strip comprising one flat lateral edge, an opposite rounded resilient edge, spaced ribs formed between said edges and adapted to fit into the recesses in said sash, one of the side walls of each rib being pitched at an acute angle to the other side wall for disposal in the bevelled portion of a sash recess, and base portions connecting said ribs and rounded edges.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature.

OTTO KRESSER.
